  • Chirping/Squeaking under the hood

    Most of the time when I start up my TJ, it starts to squeak or chirp under the hood. Especialy after wet weather. this leads me to believe that perhaps my pulleys or somethign on the serpentine belt line is squeaking. I was thinking about just hitting it with some PB Buster, but I was gonna see if someone else had another way that they knew. Thanks

      Don't use lube on your belt... the whole system works on friction driving all the pulleys, if you lube them up then some of the components wont spin like they're supposed to. The chirping in wet weather is prob due to water collecting in pores or otherwise between the belt and the pulleys, slipping and grabbing causing the rubber to squeak fast on the metal.

        you can hit it with WD40 and let that go for about a week any more and you asking fro trouble. that way you can make it to the weekend to change the belt.

          I just changed the belt here probably, six months ago, maybe a little more. I talked to a buddy about it and he said something about sprinkling some baby powder on the belt and it will stop the chirping. Anyone heard of anything like this?

                When you do maybe you could get one of those gator grip belts (the kind with cross hatching). I've had alot better luck with those.

                  I've heard about doing this also with talcum powder. Or even with chalk.

                    Do you have a idler pulley? Not familiar with TJ's but I would imagine it does. A idler pulley will make some chirping sounds. They are usually around $15-$20. Wouldn't hurt to change it anyway.

                          Yes it is an autotensioner, I am going to change the belt and just see if that fixes it. I guess I just won't buy the cheap belts anymore.

                            I would change the idler pulley (or tensioner pulley) while your at it. IMO
